QQuaternion¶

PyQt5.QtGui.QQuaternion

Description¶

The QQuaternion class represents a quaternion consisting of a vector and scalar.

Quaternions are used to represent rotations in 3D space, and consist of a 3D rotation axis specified by the x, y, and z coordinates, and a scalar representing the rotation angle.

length() → float: Returns the length of the quaternion. This is also called the “norm”.

lengthSquared(), normalized().

lengthSquared() → float: Returns the squared length of the quaternion.

@staticmethod nlerp(QQuaternion, QQuaternion, float) → QQuaternion: TODO

normalize(): Normalizes the current quaternion in place. Nothing happens if this is a null quaternion or the length of the quaternion is very close to 1.

See also

length(), normalized().

normalized() → QQuaternion

Returns the normalized unit form of this quaternion.

If this quaternion is null, then a null quaternion is returned. If the length of the quaternion is very close to 1, then the quaternion will be returned as-is. Otherwise the normalized form of the quaternion of length 1 will be returned.

__repr__() → str: TODO

__rmul__(float) → QQuaternion: TODO

rotatedVector(QVector3D) → QVector3D

Rotates vector with this quaternion to produce a new vector in 3D space. The following code:

#     QVector3D result = q.rotatedVector(vector);

is equivalent to the following:

#     QVector3D result = (q * QQuaternion(0, vector) * q.conjugated()).vector();
